Introduction

\n

The Embedded Capacity Register (ECR) lists all generation, storage, and flexible demand resources where the installed generation capacity, export capacity, or import capacity is 50kW to 1MW.

Note: Please note, in the\u00a0November 2025 publication, an additional 230 records were included. This data has been provided by MCS (Microgeneration Certification Scheme) where installers have not previously notified us of installations.\u00a0 In publishing the data we aim to provide greater visibility of the number of installations.
